 查看用户HN_KW下的所有表的总记录数：

SELECT SUM(num_rows) FROM SYS.ALL_TABLES T WHERE T.OWNER = 'HN_KW';

 查看用户HN_KW下的各表的总记录数：

SELECT t."OWNER",t.TABLE_NAME,t.NUM_ROWS FROM SYS.ALL_TABLES T WHERE T.OWNER = 'HN_KW' ORDER BY num_rows DESC;

查看用户HN_KW下所有表的字段总数：

SELECT * FROM SYS.dba_TAB_columns T WHERE T.OWNER = 'HN_KW';

Oracle查询数据库中所有表的记录数：

select t.table_name,t.num_rows from user_tables t;
